APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday May 14, 2026 (SJD 61175) ---- Observing Team ---- Conner Scoresby ---- Observing Plan ---- Thu 14 May 2026 61175 0.04 02:54 03:11 10:47 11:39 19:16 --- dark ( 7.6 h) plus 1.2 h for 8 deg design ---- Observing Summary ---- Most of the night was lost due to weather. We had some scattered radar throughout, and pollen was a concern for the first half. The particulates calmed down, and we were able to get the last 2.5 hours of the night on sky. Completed 8 bright time designs. Notes: 1. Opened for 15 minutes at 5:15Z but closed before any calibrations were taken. The telescope altitude brake was causing problems moving to and from 5 degrees; closed soon after because radar cropped up again. The issue wasn't seen again, more details in log body. 2. Dust collected ~2200 dust-hours ---- Automatic Summary ---- Time Field-Design-Conf DesignType BOSS/APOGEE Seeing Overhead Complete?

Thought I saw a 'frame break' error fly through the log. The telescope would move ~3 degrees before stopping and engaging the stops. Cycled stop buttons, cycled wind baffle, and eventually the telescope moved to 5 with the script. However, the 15 degree stop was hit. Stopped the telescope, went back to stow, and tried again to 5 degrees with no other issue. Once the enclosure was open, the telescope had the same trouble trying to go back to stow. I figured it had something to do with the enclosure, so I closed again, and the telescope moved with no issues to and from 5 degrees. Radar cropped up during this time anyway, so I attribute no time lost to mechanical issues. We stayed closed for three more hours, and that time opened up with no problems. ---- Observing Log ---- Afternoon disk space check: /dev/sdb1 2.0T 502G 1.6T 25% /home /dev/sdd1 22T 14T 7.2T 66% /data 22:48Z Tested actors, all systems live.

The telescope was being very finicky trying to get it to 5 degrees. I think it hit the 15 degree stop once it finally moved from stow. After stopping and examining what could have made it stop and finding nothing, it was moved back to stow before trying 5 degrees again. No issues this time. But after opening the enclosure, the telescope refused to move back to stow. After ten minutes of troubleshooting, decided to close the enclosure again (pollen was pretty high and there are some local radar blips), the telescope moved back and forth between 5 and 30 degrees altitude without issue (exercised it several times). Ventilation suspended. 08:24Z Ventilation resumed. 05:16Z Enclosure opened to clear skies. 08:54:09 hal apogee-dome-flat: FFS, shutter, expose 08:54:32 APOGEE expNum=56130011, reads=5, dithPos=B,
